Answer:
The eggs are kept in a cool place so that they can be stored for a long time. In a favourable condition,they hatch into larva. Larva are produced in about 2 weeks from eggs at a temperature of 18 to 25 degree Celsius
Explanation:
Answer:
Depending on the food pyramid, on the side there may be something that says decomposers. These eat from all of the sections of the pyramid.
Energy flows from the bottom to the top, and then to the side with the decomposer.
The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
Answer:
A.
Explanation:
Older fossils tend to lay in the lower levels of the ground. The further up the fossils are, the more likely you are to find something that looks like today. Think of it as stacking papers with different drawings on them from different ages. Oldest goes on the bottom, newest goes on the top. The older layer stands as more of a foundation point while newer layers are around where we are now.
In order to survive the winter, monarch butterflies "migrate to warmer areas".
<u>Option: B</u>
<u>Explanation:</u>
- The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
- This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
- Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
- If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
